Question

0.1 gram mole of urea is dissolved in 100g of water.the molality of the solution is

Answer 1

here is ur answer
the molality is 1m

Answer 2

Answer: The molality of the solution is 1m.

Explanation:

Molality is defined as the number of moles of a substance present in a 1 kilogram of a solution.

Mathematically,

[tex]\text{Molality}=\frac{\text{Number of moles of substance}}{\text{Mass of solution (is kg)}} [/tex]

We are given:

Moles of urea = 0.1 moles

Mass of the solution = 100 g = 0.1 kg       (Conversion factor: 1 kg = 1000g)

Putting values in above equation:

$\text{Molality of the solution}=\frac{0.1mol}{0.1kg}=1m$

Hence, the molality of the solution is 1m.
